Description

Key input interface method

TECHNICAL FIELD The present invention relates to key input interface technology, and more particularly, to key input interface technology that enables more inputs with only a limited number of keys in a small electronic device.

Mobile terminals such as mobile phones and PDAs are not only miniaturized with the development of semiconductor technology, but are also becoming mini computers as their functions are diversified. However, the input means prevents the miniaturization of the portable terminal. In the early days of the portable terminal, the input means simply required character input, so only a limited number of buttons were sufficient. Now, the input means requires an input means as much as a keyboard. Therefore, in the related art, a method of miniaturizing a general keyboard to be physically coupled to a portable terminal can be used. However, since a user's input must be considered, there is a limit to miniaturization, which in turn causes an increase in volume.

SUMMARY OF THE INVENTION The present invention is derived from this background, and an object of the present invention is to provide a key input interface method that enables all the inputs required in electronic devices, particularly in electronic devices that are not sufficiently equipped with hardware button means for miniaturization.

According to an aspect of the present invention, there is provided a key input interface method comprising: allocating key elements classified into a first group and a second group to a key array; And processing a key element assigned to the selected key as an input, recognizing a key element selection method, and processing a key element belonging to the corresponding group among the first group and the second group as an input.

The assigning step allocates at least one key together with at least one key element belonging to the first group and at least one key element belonging to the second group.

The method further includes providing a screen interface for key selection.

The input processing may include selecting a partition region through a screen interface; Determining a manner in which the partition is selected; And inputting a key element belonging to a first group or a second group assigned to a key corresponding to the selected partitioned area according to the determined selection method.

The present invention divides a plurality of key elements into a first group and a second group and assigns them to a limited number of key arrays, and selects an interface scheme and a key element belonging to a second group. By presenting a concrete way to change the interface method to select, it is possible to input a sufficient key even with a limited number of keys in a small electronic device.

In particular, the present invention makes it possible to distinguish between the first group of key elements and the second group of key elements by varying the selection method, thereby allowing a large number of key elements to be assigned to a limited number of key arrays at one time. This creates the effect of minimizing the need to change a new arrangement of key arrays for new key element inputs.

The foregoing and further aspects of the present invention will become more apparent through the preferred embodiments described with reference to the accompanying drawings. Hereinafter, the present invention will be described in detail to enable those skilled in the art to easily understand and reproduce the present invention.

1 is a flowchart of a key input interface method according to the present invention.

The key input interface application according to the present invention is implemented in an electronic device. The electronic device may be a mobile phone, a personal digital assistant (PDA), a smart phone, or the like. When the key input interface application implemented in the electronic device is executed (step S100), it is assigned to a key arrangement having a limited number of keys classified into the first group and the second group (step S110). In one embodiment, the key arrangement is a matrix structure, for example, three rows and three columns. However, this is exemplary and the key arrangement may be in various forms. The key elements are classified into a first group and a second group. The criteria classified into the first group and the second group may be the characteristics of key elements, but are not limited thereto. That is, the manner of classifying the key elements into the first group and the second group is outside the scope of the present invention.

On the other hand, in step S110, at least some matrix keys are assigned together with key elements belonging to the first group and key elements belonging to the second group. In addition, in step S110, a plurality of key elements belonging to the first group may be assigned to a single matrix key together, and a plurality of key elements belonging to the second group may be assigned together to a single matrix key. For convenience of description, key elements belonging to the first group are referred to as alpha (α) keys, and key elements belonging to the second group are referred to as beta (β) keys.

The matrix structure in which alpha keys and beta keys are arranged is displayed as a key map (step S120). The user can input alpha key or beta key by referring to the key map. In addition, a screen interface for key selection is provided, and at least a partial area of the screen is divided into three rows and three columns, and the divided whole area is provided as a screen interface (step S130). In some cases, for example, when there is a user request through the user interface, a division line for dividing the entire area is displayed on the screen, so that the user can intuitively distinguish the divided areas.

If there is a selection in the partition area by the user, the selection method in the partition area is determined (step S140) (step S150). The selection method may be various, and for example, may be a touch or stroke method. If the selection method is determined, an alpha key or a beta key input assigned to a key corresponding to the selected partition area is processed according to the determined selection method (step S160). For example, if the selection method is a touch method, an alpha key assigned to a key corresponding to the selected partition is input. If the selection method is a stroke method, a beta key assigned to a key corresponding to the selected partition is input.

Meanwhile, the key input interface according to the present invention supports a text mode and a keyboard mode. The text mode refers to a mode in which general letters, numbers, symbols, and the like can be input. The keyboard mode refers to a mode in which other inputs of the keyboard are possible other than general letters, numbers, and symbols. Switching between the text mode and the keyboard mode is performed by key input, and in each mode, various key inputs are possible by assigning a new key element used in the corresponding mode according to the key input. This is described in detail in the Appl. No. 10-2006-135001 filed by the applicant on December 27, 2006.

Therefore, inputting an alpha key or a beta key by step S160 may be referred to as performing an action according to the meaning of a corresponding key element, switching a mode, or processing a new key assignment in the current mode.

2 is a reference diagram in which alpha keys are assigned to a key arrangement in a three-row, three-column structure, and FIG. 3 is a reference diagram in which beta keys are assigned to a key arrangement in a three-row, three-column structure, and FIG. 4 is an alpha key and beta keys. This is a reference diagram assigned to the key array of this 3-row and 3-column structure. The present invention proposes a technical solution that can be selected even if the alpha key and beta keys are assigned together as shown in FIG. 4, so that alpha and beta keys assigned to one key can be distinguished and input. In these figures, the meaning of {α} or {β} means that multiple alpha or beta keys can be assigned.

5, 6 and 7 are exemplary diagrams of alpha key and beta key assignment in text mode.

In text mode, you can see that key elements that are classified as alpha and beta keys are assigned to the same key. Furthermore, FIG. 5 and FIG. 7 illustrate that alpha keys may be assigned to a single key, and that beta keys may also be assigned to a plurality of keys through row 3, column 1 of FIG. 7.

5, 6, and 7, the 'tab', 'bspace', 'enter', and 'space' key elements are always fixedly assigned in the text mode. It can also be seen that the position is fixed. For reference, 'bspace' here means 'backspace'. Since these key elements are frequently used in the text mode, it is desirable that they are always fixed and remain unchanged even when a new key element is assigned in the text mode.

In addition, these key elements are preferably assigned to a three-row, three-column array in consideration of their position on the keyboard. As shown in FIG. 8, 'tab' is located on the left side of the keyboard, 'bspace' is located on the right side, 'enter' is located on the right side, and 'space' is located below, 5, 6, 7 Assign the 'tab', 'bspace', 'enter' and 'space' key elements to match the layout on the keyboard as in.

5, 6, and 7 it can be seen that the key element 'keybd' is fixedly assigned in the text mode. This 'keybd' key element is a key element for switching from text mode to keyboard mode, and is most preferably assigned to 2 rows and 2 columns.

9, 10, and 11 illustrate example alpha and beta key assignments in the keyboard mode.

As in the text mode, it can be seen that key elements classified as alpha and beta keys are assigned to the same key together. Also, although not illustrated, alpha keys may be assigned to one key in a plurality, and beta keys may be assigned to a single key, as in the text mode.

Meanwhile, it can be seen from FIGS. 9, 10, and 11 that the key elements 'ctrl', 'shift', 'alt', and 'win' are always fixedly assigned in the keyboard mode. It can also be seen that the position is fixed. Since these combination key elements are frequently used in the keyboard mode, it is desirable that they are always fixed and remain unchanged even when a new key element is assigned in the keyboard mode. These combination key elements also preferably include all combination keys on the keyboard as shown in FIG. For example, some keyboards include an "option" key instead of a "win" key and may also contain other combinations.

9, 10, and 11 it can be seen that the 'text' key element is fixedly assigned in the keyboard mode. This 'text' key element is a key element for switching from keyboard mode to text mode, and is most preferably assigned to two rows and two columns.

13 and 14 are exemplary diagrams of a key map and a segmented screen interface.

As shown in FIGS. 13 and 14, the alpha key array and the beta key array, which serve as key maps, are displayed at the bottom of the screen or on the right side of the screen, and the screen is divided into three rows and three columns and provided as a screen interface, thereby allowing the user to provide a key map. For reference, the screen interface divided into three rows and three columns allows you to select an alpha key or a beta key to input. Here, the screen interface is illustrated as being evenly divided into three rows and three columns except for a screen for a key map, but is not limited thereto. For example, when the key map is not displayed, the entire screen may be divided into three rows and three columns as shown in FIG. 15 to provide a screen interface, or as shown in FIG. 16, some areas of the entire screen may be divided into three rows and three columns. It may be divided evenly and provided as a screen interface.

Hereinafter, various embodiments of a method of selecting an alpha key and a beta key and a method of determining a selection method will be described.

First Embodiment

As illustrated in FIG. 17, the selection interface is divided into a touch and a stroke. In the case of touch, the alpha key is selected, and in the stroke, the beta key is selected. In addition, it is defined as selecting a divided region by directly touching or stroketing the divided region to be selected for both touch and stroke. Here, it is possible to distinguish whether the stroke is a stroke by determining whether the stroke is longer than a predetermined length in an arbitrary direction. In other words, it is determined whether the length is greater than or equal to a predetermined length based on the starting point coordinates and the ending point coordinates.

In this interface method, when the divided region of one row and one column is selected as a touch, it is determined that the selected region is one row and one column through touch sensing and touch sensed coordinate values, and as a result, an alpha key assigned to one row and one column Treat as input When the divided area of the 2nd row 1 column is selected as the stroke, it is determined that the selected area is the 2nd row 1 column based on the starting point coordinate value at which the stroke is detected and the stroke is started. As a result, the beta key assigned to the 2nd row 1 column is inputted. Process.

Meanwhile, as illustrated in FIG. 5, when a plurality of alpha keys are allocated, the selected alpha key may be determined by detecting the number of consecutive touches within a predetermined time. For example, if the partition area in one row and one column is touched once, 'e' is selected, if it is touched twice within a predetermined time, 'w' is selected, and if it is touched three times within a predetermined time, it is determined that 'q' is selected. To process the alpha key. When a plurality of beta keys are assigned, the selected beta key may be determined by detecting a continuous stroke number or a stroke direction change number within a predetermined time. For example, as shown in Figure 18, if there is no change in the direction of the stroke, the first beta key is selected, if the change of direction of the stroke occurs once, the second beta key is selected, and if the direction of the stroke occurs twice, Is to select the first beta key.

Second Embodiment

As illustrated in FIG. 19, the selection interface is divided into a touch and a directed-stroke. In the case of touch, the alpha key is selected, and in the case of directional stroke, the beta key is selected. In the case of touch, the selection is made by directly touching the divided area, while the directional stroke is defined as selecting the divided area in the direction of the stroke. Here, the direction of the stroke may be calculated from the start point to the end point through the start point coordinates and the end point coordinates.

If there is a stroke input in this interface method, it is determined that the stroke is selected based on the coordinates of the start point and the end point of the stroke, and the direction of the stroke is detected to determine which area is the selected partition, and the beta key assigned to the matrix. Treat as input For example, if the direction of the stroke is on the left, 1 row, 1 column, on the top, 1 row, 2 columns, on the upper right, 1 row, 3 columns, on the left, 2 rows, 1 column, on the right, 2 rows, 3 columns, on the left, 3 rows, 1 column, on the high side, 3 If the row 2 column and the bottom right column, the partition area of the 3 row 3 column is determined as the selected partition area, and the beta key assigned to the matrix is processed as an input.

In the directional stroke method, unlike the stroke method of the first embodiment, the divided area is not limited. In addition, although FIG. 19 illustrates that the start of the directional stroke occurs from the center, this is only an example and the starting point is not limited. Therefore, the directional stroke method provides the advantage that the user can freely stroke in the screen interface area. This advantage is especially evident in small electronic devices with small screen interfaces.

Meanwhile, in the second embodiment, like the first embodiment, a key element selected from an alpha key or a beta key assigned to a plurality of keys is detected by detecting the number of consecutive touches, the number of strokes, or the number of stroke direction changes within a predetermined time. Can be determined.

Third Embodiment

As illustrated in FIG. 20, the selection interface is divided into a single touch and a double touch. Double touch means to touch two points at the same time. In the case of single touch, the alpha key is selected, and in the case of double touch, the beta key is selected.

In this interface method, if the divided area of two rows and three columns is selected as the single touch, it is detected that the touch is once and it is determined that the two rows and three columns are selected by the single touch based on the detected coordinate value. Processes the alpha key assigned to row 3 as an input. When the divided area of 2 rows and 3 columns is selected by double touch, it detects the touch at the same time at both points and calculates the center of gravity through the coordinate values of the two touched points, indicating that the 2 rows and 3 columns with the center of gravity are selected. As a result, the beta key assigned to row 2 and column 3 is processed as an input. The reason for calculating the center of gravity here is considering a case where it is difficult to touch one divided area at the same time because the divided area is small. This is because the center of gravity of the two points is very likely to be located in the partition to be selected even if one or both touches leave the partition to be selected.

On the other hand, when a plurality of alpha keys are assigned to one key, one alpha key may be selected through consecutive touches within a predetermined time of a single touch. Similarly, when a plurality of beta keys are assigned to one key, one beta key may be selected through consecutive touches within a predetermined time of double touch.

Fourth Embodiment

As illustrated in FIG. 21, the selection interface is divided into multi-touch and stroke. In this case, the multi-touch means touching one or more points at the same time. In the case of multi-touch, an alpha key is selected, and in the case of a stroke, a beta key is selected.

In this interface method, if there are multi-touch inputs for three rows and one column, the touched points are sensed at the same time and the center of gravity is calculated using the touch-sensed coordinates to determine the partition area where the center of gravity is located. The alpha key assigned to the corresponding number of touches among the alpha keys assigned to the key is processed as an input. In this interface method, the stroke input is the same as the stroke input of the first embodiment.

Fifth Embodiment

As illustrated in FIG. 22, the selection interface is divided into multi-touch and multi-stroke. Multi-touch is defined as selecting the alpha key, and multi-stroke is defined as selecting the beta key. Multi-stroke here means that more than one stroke occurs at the same time.

In this interface method, if there is a multi-stroke input, the number of strokes is sensed at the same time, the center of gravity is calculated from the coordinates of the starting point of the stroke, and the division area where the center of gravity is located is determined, and the result is assigned to the corresponding key. The beta key assigned to the number of strokes among the beta keys is processed as an input. In the interface method, the multi-touch input is the same as that of the multi-touch input of the fourth embodiment.

Sixth Embodiment

As illustrated in FIG. 23, the selection interface is divided into multi-touch and directional stroke. Multi-touch is defined as selecting the alpha key, and directional stroke is defined as selecting the beta key. In this interface method, the multi-touch input is the same as in the fourth embodiment, and the directional stroke input is the same as in the directional stroke input in the second embodiment.

Seventh Embodiment

As illustrated in FIG. 24, the selection interface is divided into multi-touch and multi-directed stroke. Multi-touch is defined as selecting the alpha key, and multi-directional stroke is defined as selecting the beta key.

In this interface method, if there are multi-directional stroke inputs, the number of strokes is simultaneously detected and the direction of the multi-strokes is determined. As a result, the beta key assigned to the corresponding number of strokes among the beta keys assigned to the corresponding key is detected. Process as input In this process, since the directions of the multi-strokes will all be the same, the direction of the multi-strokes may be determined using the coordinate values of the start point and the end point with only one stroke. Alternatively, it may be determined by the direction of movement of the center of gravity of the contacts at every instant of these strokes. In the interface method, the multi-touch input is the same as that of the multi-touch input of the fourth embodiment.

Eighth Embodiment

As illustrated in FIG. 25, the selection interface is divided into a single touch / single directional stroke and a double touch / double directional stroke. Single touch / single directional strokes are defined as selecting alpha keys, and double touch / double directional strokes are defined as selecting beta keys.

If touch selection is made in this interface method, it is determined whether it is a single touch or a double touch. If it is determined as a single touch, the alpha key assigned to 2 rows and 2 columns is processed as input, and if it is determined as a double touch, the beta key assigned to 2 rows and 2 columns is processed as input. If there is a stroke selection, it is determined whether it is a single stroke or a double stroke, and the direction of the stroke is detected. In the case of a single stroke, the alpha key assigned to the corresponding key among the other keys except for 2 rows and 2 columns is input according to the direction of the stroke.In the case of a double stroke, the remaining keys except 2 rows and 2 columns according to the direction of the stroke Input the beta key assigned to the corresponding key.

For example, the corresponding key depends on the direction of the stroke.For example, if the direction of the stroke is on the top left, then 1 row, 1 column, on the top, 1 row, 2 columns, on the right, 1 row, 3 columns, on the left, 2 rows, 1 column, on the right, 2 rows, 3 columns 3 rows and 1 column on the left and 3 rows and 2 columns on the high and 3 rows and 3 columns on the right and bottom.

<Example 9>

A distinction is made between the alpha and beta keys by distinguishing the other two inputs from the device used for the input. Examples of these devices include a mouse with left and right buttons, or a stylus pen with pen nibs and side buttons. Clicking on the partition with the left mouse button determines the alpha key assigned to the key corresponding to the clicked area.Clicking on the partition with the right mouse button selects the beta assigned to the key corresponding to the clicked area. It is determined that the key is selected. As another example, if only the touch selection is performed with the pen tip of the stylus pen, it is determined that the alpha key assigned to the key corresponding to the selected region is selected.If the touch selection is performed while pressing the side button of the stylus pen, the selected region is selected. It may be determined that the beta key assigned to the key corresponding to is selected and processed. Further, it is determined that one of the alpha keys assigned to the key corresponding to the selected area is selected or one of the beta keys is selected according to the number of consecutive touches within a predetermined time.

Tenth Embodiment

Similar to the ninth embodiment, a method for distinguishing between alpha and beta keys by distinguishing two other inputs from a device used for input. If touch selection is made with the left button of the mouse or the pen tip of the stylus pen, it is determined that the alpha key assigned to row 2 and column 2 is selected.If touch selection is performed with the right button of the mouse or the side button of the stylus pen is pressed, 2 It is determined that the beta key assigned to the row 2 column is selected. If you select a stroke with the left button of a mouse or the pen tip of a stylus pen, input the alpha key assigned to the corresponding key among the remaining keys except 2 rows and 2 columns according to the direction of the stroke.Use the right button of the mouse or the stylus for processing. If you select a stroke while pressing the side button of the pen, the beta key assigned to the corresponding key among the other rows except for 2 rows and 2 columns is processed according to the direction of the stroke.

<Eleventh embodiment>

This method distinguishes alpha key and beta key by using a supplementary key other than an array of 3 rows and 3 columns. In this case, the modifier key can act as a 'shift' key. In other words, if touch selection is performed while the auxiliary key is not selected, the alpha key assigned to the selected key is selected. If touch selection is selected while the auxiliary key is selected, it is determined that the beta key assigned to the selected key is selected. To deal with. Furthermore, among the same key elements assigned to the selected key, the selected key element is determined and inputted according to the number of consecutive touches within a predetermined time.

<Twelfth Example>

How to distinguish between alpha key and beta key using touch time. If the touch time is less than a predetermined time, it is determined that the alpha key is selected. If the touch time is more than the predetermined time, it is determined that the beta key is selected. Furthermore, among the same key elements assigned to the selected key, the selected key element is determined and inputted according to the number of consecutive touches within a predetermined time.

<Thirteenth Embodiment>

This method distinguishes alpha and beta keys using touch intensity. If the touch intensity is less than a certain intensity, it is determined that the alpha key is selected. Furthermore, among the same key elements assigned to the selected key, the selected key element is determined and inputted according to the number of consecutive touches within a predetermined time.

On the other hand, the key input interface method according to the present invention can be created by a computer program.
